SPECIFICATION forming part of Letters Patent No. 392,533, dated November 6,1888.

Application tiled July 25, 1388. Serial No. 281,040. (No model.)

To @ZZ whom it may concern:

Be it known that I, J osnrI-I C. BIRD, acitizen of the United States, residing at Itising Sun, in the county of Cecil and State of Maryland, have invented certain new and useful Improvementsin Gultivator-Spindles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates particularly to animprovement in spindles for wheel-cultivators, and hasfor its object the production of a device of this character in the use of which the wear of the journals may be conveniently compensated at small expense, and which may be readily attached to or detached from any wheelcultivator provided with an arched axle.

In wheel-cultivators as commonly constructed an arched axle is used, so that the machine may ride over the young plants without injuring them; but the wheel-spindles are integral with the main portion of the axle, and when the wheels become loose on their bearings from wear the machine must be used in the inferior condition or a new axle entire must be substituted at considerable trouble and expense.

It is the object of my invention to overcome this difliculty by making the part of the arched axle on which the wheel turns detachable, so that a new journal may be cheaply and readily inserted by the operator.

To these ends my invention embodies certain features, which will be hereinafter clearly described in the specification, and then delinitely indicated in the accompanying claims.

In the accompanying drawings, which illustrate my invention, Figure 1 is a perspective view showing the device as attached to the arch and draft-beam of a cultivator. Fig. 2 is a rear partly sectional view showing the wheelhub in place on the spindle. Fig. 3 is a side view, part being shown in section on the line a: a: of Fig. 2. Fig. e is a view of the sandguard detached.

9 is the draft-beam of the cultivator; and 8 is one limb of the arched axle on the left side of the cultivator, looking from the rear.

the limb 8 is attached, by bolts and nuts, as shown, a metallic support, 1, provided with a curved or recessed part, 3, at its lower end and a bottom ear or lug, 5. The curved or recessed partincloses substantially one half of the spindle 7, the other half being inclosed by a co-operative piece attached to the draft-beam 9, said piece having a horizontal extension, 2, and an ear, 6, parallel to the ear 5 of the other support when the parts are assembled. The recessed parts thus constitute two jaws which iirmly grip the spindle when they are tightened over it by the bolts and nuts. The front support is also provided with vertical ears 6 and 15. Bolts 16 17 and 18 19 and. their cooperating nuts grip the spindle iirmly between the two curved parts. A metallic sleeve, 10, ts over the spindle so as to freely turn on the same. This sleeve is provided with an opening, 20, in which the head of a bolt, 21, may be seated, the stem of the bolt extending through the hub of the wheel and being provided with a nut, as shown, so as to rmly lock the sleeve in the hub. Vhen the sleeve has been secured in the hub, the wheel is slipped over the spindle and held in place by a retainingring and set-screw, 12.

From the organization described it will be seen that the wear in the use of the machine is confined to the spindle 7 and sleeve 1l), and that when said wear becomes so great that it will interfere with a perfect operation of the machine these two parts can be removed and new ones substituted. As these parts are made of 8 5 cast metal, they can be furnished very cheaply.

In order to prevent sand or earth lifted by the wheel from falling upon the wheel-bearing and increasing the wear, I provide a shield, 13, shown in plan in Fig. 4, and provided with an ear, 111, slotted, as shown, so as to admit one of the bolts, 1G, which pass through the clamping-jaws. This sand-shield is shown in position in Fig. 1.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. lI he combination, with a cultivator-arch, of a spindle-support comprising the separable jaws, as 1 and 4, a spindle secured thereby, a removable metallic sleeve on said spindle, adapted to be secured to the hub, and means for preventing the sleeve from slipping off the clamping-piece co-operatingwithsaid support, spindle, as and for the purpose described. said clamping-piece having a horizontal ear 2.
